| Abstract | ||
| The effect of some alternative fertilizers, namely anhydrous ammonia in comparing with urea, humic acid, rock phosphate and feldspar on growth, yield and its components and nutrient uptake and its availability in soil after harvest for wheat plant (cv Beni Swif 1) were evaluated in a field experiment. The experiment was conducted at Sids Agricultural Research Station (ARC) Beni Swif Governorate 2010/2011 and 2011/2012 seasons in split plot design. Nitrogen sources, i.e. anhydrous ammonia or urea at rate of 75 kg N/fed were located in the main plots. While, natural fertilizer treatments (without, humic acid, rock phosphate, and feldspar and their combinations at rates of 10, 300 and 400 kg/fed respectively) were added in the sub plots. The results show that anhydrous ammonia significantly produced tallest and heaviest plants, more numbers of both spikes/m2 and grains/spike as well as higher 1000 grain weight and grain and straw yields when compared with urea. Also, plants incorporated with anhydrous ammonia absorbed more N, P and K than that with urea. Injected the soil with anhydrous ammonia significantly improved soil available nitrogen after wheat harvest, while soil available P and K were not affected. The treatments effects of natural fertilizers comparing with, without natural fertilizers on growth parameters (plant height, dry weight/plant, number of spikes/m2, number of grains/spike and grain and straw yields) could be arranged in the following descending order: humic acid > rock phosphate > feldspar. Combined humic acid with rock phosphate and /or feldspar were enhanced its effects than sole applications. Humic acid, rock phosphate or feldspar yielded highest N, P and K uptake by grain and straw, when compared with control. Combined natural fertilizers with each other produced more nutrient uptake than the single one. Humic acid application enhanced soil available N, P and K, however rock phosphate and feldspar significantly improved soil available P and K, respectively than untreated control. | ||
